Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to improve the uniformity of distribution of fertilizers across the width of the grip and increase productivity. The machine comprises a body 1 with a feed conveyor 2, a metering slide 3. The invention relates to the field of agricultural engineering, in particular, to machines for fertilizing and chemical ameliorates to the soil. The purpose of the invention is to improve the uniform distribution of fertilizers across the width of the pickup and increase productivity. FIG. 1 shows a fertilizer and chemical ameliorating machine, top view; FIG. 2 is the same, side view; FIG. 3 shows the node I in FIG. 1. with a handwheel 4 and a metering orifice 5, a chopping drum b and a distributing working body (PO) 7 in the form of components 8.9 with paddles (L) 12 fixed along a helical line. In order to increase the uniformity of distribution of fertilizers and chemical ameliorants across the working width and increase the productivity, RO 7 is equipped with screw windings (HV) 10, 11 mounted on the cylinder along the line L 12. The length L 12 is greater than the height HH 10, 11, increasing for each subsequent L 12 from the edge of PO 7 to the center by an arithmetic progression, the angle between the extreme plane of L12 and the tangent plane to HH 10, 11 along the intersection line L 12cBH 10, 11 is 150–153 °, and the installation angle of each subsequent L 12 from kra RO 7 to the center along the move Machine voltage lower by 4-5 ° while maintaining the overlap between adjacent L 12s. When spreading fertilizers from the body 1 L 12 PO 7, the mass of fertilizers is spread across the width of the grip by the fans in a given direction. 1 hp f-ly, 3 ill. The fertilizer and chemical ameliorating machine consists of a body 1 with a feed conveyor 2, a metering valve 3 with a handwheel 4 and a metering hole 5.

Description

Screw coils 10,11 with blades are fastened to the working body 7. The blades 12 are fixed on screw windings 10 and 11 perpendicular to the surface of the component parts 8 and 9 of the distributing working body 7 by their longitudinal axis. The length of the blades 12 is greater than the height of the screw windings 10,11 and not the same width of the distribution of the distribution of the working body 7, increasing in arithmetic progression from the ends of the distribution working body 7 to its center. The angle () between the plane of the end blades 13, 14 of the left 8 and the right 9 components of the distribution tool 7 and the tangent plane to the screw windings 10, 11 along the intersection of the blades 13 and 14 with the screw windings 10 and 11 is 150 - 153 °. Angles (pi, rz) setting each subsequent blade 12 from the ends of the distribution of the working body 7 to its center less by 4 - 5 ° while maintaining the overlap between adjacent blades 12. Distributive working body 7, grinding drum 6 and the feed conveyor 2 through the drive mechanism 15 St. zan with two tractor tor. The left 8 and right 9 components of the distributor working body 7 are connected with the drive mechanism 15 and among themselves by means of hinged connections 16.

The machine works as follows.

Fertilizers or chemical ameliorants loaded into the back of one of the machines are transported to the field by a tractor. At the place of their introduction, rotating the handwheel 4, move the metering gate 3 upwards and set the size of the metering slot 5 corresponding to the set fertilizer dose. After turning on the tractor's power take-off shaft, the unit starts driving across the field. Rotation from the tractor's power take-off shaft through the drive mechanism 15 is transmitted to the chopping drum b, the feeding conveyor 2 and through the joints 16 to the distributing working part 7 of its left 8 and right 9 integral parts. The feed conveyor 2 discharges through the metering orifice 5 a layer / goodness or chemical ameliorants, which are fed to the grinding drum, are loosened and transferred to the distributing working element 7. Screw winding 10.11, blades 12 left 8 and right 9 component parts of the distribution worker organ 7 pick up fertilizers, chemical ameliorants and scatter them along the way, to the left and right sides of the axis

movement of the machine. Blades 12 of greater length throw fertilizer to the sides further.

Blades 12, the length of which decreases from the center of the distribution worker

body 7 to its ends, provide a uniform distribution of fertilizers on the soil, increase the width of the grip. The blades 12, rotating together with the left 8 and right 9 components of the distributor working body 7, spread fertilizers and chemical ameliorants in different directions relative to the machine’s axis of motion in the form of fans. The setting angle () of the outer blades 13, 14 ensures optimal

The conditions of fertilizer release from the surface of the blades and more than other blades deflects the sifting fan left and right from the axis of movement of the machine, increasing the uniformity of the distribution of fertilizers and the width

Capturing the unit After releasing the body 1 from the fertilizer, the unit returns for loading. In comparison with the prototype, the proposed machine allows to reduce the uneven application of fertilizers and
